Is Microsoft SteadyState useful ? Did not work so well for me

Featured Windows Download: Windows SteadyState Creates a Wreck-Proof Space for Kids, Experiments

Windows XP/Vista only: SteadyState, a free Windows utility offered by Microsoft, is a handy tool to have if you’ve got kids, friends, or just a program or two that could possibly wreak havoc on your system

It did not work so well in my experiment. I turned on Protect Hard Disk and Preserve Changes Permanently. The PC froze 2 times during restart when it was committing the changes ie making the changes permanent.

My PC also ran significantly slower with Steadystate.

With the above problems, I uninstalled Steadystate.
